Arduino API

RoboBoard X4 implements standard functions from Arduino Reference.

Multithreading

Arduino implementation for RoboBoard X4 allows for easy multithreading in the projects. It introduces addLoop() function to create multiple parallel loop() functions.

addLoop(function)

Register new parallel loop() function.
Parameter:
function - parallel function name (loop2())

// Variables to hold count for each loop
int counter2 = 0;
int counter3 = 0;
int counter4 = 0;
// Arduino loop (default)
void loop() {
  // Print loop counters
  Serial.printf("%08lu: loop2: %3d, loop3: %3d, loop4: %3d\n",
    millis(), counter2, counter3, counter4);
  // Delay printing for 100ms
  delay(100);
}
// Loop 2 function
void loop2() {
  counter2++; // Increment counter
  delay(100); // Delay counting to 100ms
}
// Loop 3 function
void loop3() {
  counter3++; // Increment counter
  delay(500); // Delay counting to 500ms
}
// Loop 4 function
void loop4() {
  counter4++;  // Increment counter
  delay(1000); // Delay counting to 1000ms
}
// Arduino setup
void setup() {
  // Start serial communication
  Serial.begin(9600);
  addLoop(loop2); // Start parallel loop2
  addLoop(loop3); // Start parallel loop3
  addLoop(loop4); // Start parallel loop4
}
